Tizip Ringseal


The TIZIP RINGSEAL is a circular MASTERSEAL 10, produced by assembling a sturdy plastic spiral to a high strength profile, welded on polyurethane tape. Each part of the spiral is inserted and well secured in a plastic profile. When the zipper is closed, the external and internal surfaces are compressed for a perfect seal.

The entire plastic profile is highly resistant to abrasion.
Unique design prevents slider detachment.
The structure of the hinge guarantees an increase in tightness, with increasing pressure, or transversal tension: both situations generate a high mechanical pressure on the upper contact surface.


The Ringseal version resists (laboratory test) up to 500 mbarof pressure (air) for the chain part.
The closing plastic cover is waterproof but the pressure seal is not evaluated.

Dust or sand

The TIZIP MasterSeal 6 is highly resistant to damage caused by dirt or sand. However if dirt or sand are present, the zipper should be cleaned with soap and water.
Dirt particles can aff ect the sealing function if they get caught between the chain profiles.
If the hinge is used to protect sensitive materials, frequent cleaning and thorough inspection before each use is essential.


No hinges are previously lubricated. However, lubrication is essential to maintain ease of use and perfect coupling of the chain.
After installing the hinge to the product, it is recommended to lubricate the entire chain and slide the slider from one end to the other, at least 5 times in both directions.
Acid free lubricants, greases and oils can be used.
Initial lubrication over the entire chain is essential.
If the chain appears dry, the user will need to lubricate the hinge periodically (approximately every 10 uses).
It is recommended to consult the instructions and use the lubricant supplied with each hinge.
The lubrication of the external surfaces allows a better handling of the cursor.


To ensure waterproofing, the hinge, in moving the slider, requires a slightly higher force than that used for standard plastic hinges. Please allow a slightly higher pulling force to undock the both ends closed version. Some lubrication can help to reduce the pulling force on the docking end. The chain is maintenance free.


The performances of the hinge in terms of resistance and durability are of a high level. Withstands sudden weight loads, abrasions and withstands short bends and twists.
Closed the zipper resists transversal traction of 300 N / cm. In case of accidental opening due to excessive tension, return the cursor to the initial position, reduce the tension on the spiral and close the zipper.
The zipper is not damaged by this procedure.
If the accidental opening of the hinge occurs up to the lower terminal, the first 2 centimeters of the spiral must be assembled by hand, before returning the cursor to the initial position.


  • 500 mbar per chain
  • tape width 70 mm
  • chain width 11 mm
  • terminal extensions 25 mm
  • zipper length: the zipper is measured including stops. To find the size of the chain, subtract about 2 cm.


The waterproof capability of the zipper is tested by placing the zipper on a horizontal rectangular frame.
The inside of the zipper is submerged while the outside is pressurized with air.
The test is passed if there are no air bubbles for at least 20 seconds.
Sample tests are carried out in each batch during production.
